Who should NOT buy

We believe that the Escalante Racer is best suited for runners with strong calves and feet accustomed to zero-drop footwear with minimal cushioning.

If this doesn't describe you, we suggest exploring alternatives like the Nike Streakfly or the New Balance FuelCell Rebel v4—both offer more cushioning and a higher drop, making them more forgiving options.

Furthermore, we do not recommend the Escalante Racer for adding significant daily miles due to its lack of foam. For runners looking for an Altra shoe better suited for everyday use, we recommend checking out the Altra VIA Olympus 2. We found it offers a real zero-drop experience but adding a tonne of cushioning underfoot.

Breathability

Our first assessment of the Escalante Racer's breathability began with our smoke test, where the knit upper truly excelled, earning a perfect score of 5 out of 5 for its exceptional ventilation.

To better understand where the shoe is most breathable, we moved the cut-in-half shoe over a powerful light. This revealed all the ventilation holes clearly, demonstrating that the midfoot also enjoys fantastic airflow—an impressive feature.

Previously, we noticed significant gaps between the threads in the knit and wanted a closer look.

Using a microscope, we indeed discovered very large holes that allow air to pass through effortlessly, making this shoe outstanding for hot summer runs.

Finally, upon closely examining the Escalante Racer's upper, we felt the knit pleasant to the touch and stretchy, although it's not focused on comfort at all.

Durability

Toebox durability

The Altra Escalante Racer seemed set for a challenging outcome in our toebox durability test, given its two features prone to issues—numerous ventilation holes and a knit fabric instead of the tougher engineered mesh.

However, we must applaud Altra for surpassing our expectations in this rigorous test, impressively scoring a 4 out of 5.

Heel padding durability

With our excitement sky-high, we continued using the Dremel, this time concentrating on the heel padding. Same specs (3.2N @ 5K RPM) too.

The outcome was equally impressive, scoring a 4 out of 5. This ensures that even for those who tend to wear down their shoes in the Achilles area, this shoe will hold up well.

Outsole hardness

Shifting our focus to the outsole, we began by testing the rubber's hardness, which registered at 75.6 HC.

Altra Escalante Racer outsole

The outsole incorporates Altra's FootPod technology, designed to mimic the foot’s anatomy, ensuring proper flexing for a more natural and smooth ride.

This moderately soft consistency enhances grip, which is beneficial for traction, though it might raise some concerns regarding its longevity.

Outsole durability

We fired up the Dremel for the last time with the Escalante Racer.

After using the tool, we observed a 1.1-mm indentation. While this result isn't alarming and aligns well with our earlier findings, we still anticipate that this rubber might not endure as long as that of a more durable road daily trainer.

Outsole thickness

Finally, we measured the outsole using our vernier calipers and recorded a thickness of 2.4 mm.

This is relatively thin compared to most shoes, but it’s an ideal choice for a shoe designed for speed and lightness. It’s a trade-off—you can’t have everything in one shoe!

Weight

We just talked about lightness, and the Escalante Racer truly embodies this feature.

Weighing in at just 7.3 oz or 208g, this shoe feels almost invisible on your feet, particularly if you're accustomed to heavier shoes for your daily training sessions.

Cushioning

Heel stack

Anyone examining this shoe will notice that it is a stark contrast to today's popular maximalist designs like the ASICS Superblast. It's actually the exact opposite, featuring a very thin midsole that aims to connect you with the ground rather than isolate you from it.

With its 19.0-mm stack height, those seeking substantial cushioning might find this shoe unsuitable. However, fans of a more grounded and natural feel—where your feet and legs are truly working—will find the Escalante Racer to be exceptionally rewarding.

Forefoot stack

We measured the forefoot at 18.5 mm, which is nearly identical to the heel's stack height, deviating just 0.5 mm likely due to slight compressions or manufacturing tolerances.

Drop

The slight 0.5 mm deviation we noted is naturally due to the shoe's zero-drop, minimalist design.

Although it doesn't achieve a perfect 0-mm drop, it comes much closer than most shoes, which typically show larger deviations from their stated drop.

Midsole softness

Note: a low durometer measurement equals a soft material, whereas a high measurement means it's firm.

Moving to the midsole, we discovered that Altra employs its TPU-based EGO foam combined with InnerFlex technology, which enhances the foam's natural flexing ability to better suit the feet.

Our Shore A durometer testing gave a reading of 30.8 HA, confirming our observations during the test runs—it's definitely a shoe designed for those who prefer a firm feel underfoot.

We must remember that this shoe has barely 2 centimeters of separation between the feet and the ground. Opting for softer, compliant formulations could lead to excessive compression with each stride, which would not be ideal.

Difference in midsole softness in cold

This shoe isn't the best choice for winter due to its high breathability, but if you choose to wear it in colder weather, the good news is that the foam only becomes 19.9% firmer, which isn't too drastic.

However, remember it's wise to pair it with thick socks if it's really cold.

Stability

Lateral stability test

The Escalante Racer brings you closer to the ground with its low stack height, offering solid stability for neutral runners and even those with mild pronation.

We found it consistently supportive across various paces, maintaining a natural running feel without any intrusiveness. And it achieves this without guide rails, plates, TPU inserts, or any additional support stuff.

Torsional rigidity

Given its minimalist, flexible approach, we anticipated rating the Escalante Racer a 1 out of 5 in this test, and indeed, that's the score it received.

We were able to twist it effortlessly, encountering almost no resistance!

Heel counter stiffness

The heel counter is subtly integrated, offering some stiffness (rated 2 out of 5 in the lab) to add a bit of structure and stability in the rearfoot.

We found this to be a smart choice, as it enhances support without compromising the shoe's minimalist feel.

Midsole width in the forefoot

We began by measuring the midsole at the forefoot, which came to 113.3 mm. This dimension is fairly standard, and seems to us like a no-risk approach from Altra.

Midsole width in the heel

On the other hand, the heel is quite narrow at just 78.6 mm.

However, it's important to remember that we're dealing with a zero-drop shoe designed to encourage forefoot striking. Adding a wider heel would only increase the weight and make the shoe feel bulkier.

Rocker

Heel-to-toe rocker? NO!

The Escalante Racer is dedicated to delivering a pure, natural running experience—adding a rockered shape would completely alter that. We found this shoe is pancake flat, really making our feet engage and work hard.

Flexibility

Stiffness

The definitive test of the Escalante Racer's minimalist, ultra-flexible design came with our 90-degree bend test.

We only needed to apply 10.9N of force, which confirms that the shoe flexes seamlessly in every stride. This bends-like-a-yogi flexibility is truly amazing!

Size and fit

Toebox width at the widest part

In our lab, we measured the widest part of the toebox at 101.9 mm, confirming a wide and roomy fit that's typical of an Altra shoe, just as we anticipated. This design ensures comfort for nearly all foot types.

Toebox width at the big toe

One measurement we always look forward to with Altra shoes is the width at the big toe area, because of its FootShape proprietary design.

Indeed, it impressed us once again, measuring a generous 92.5 mm. This substantial width is precisely why the shoe feels incredibly roomy—a perfect fit for those concerned about toe splay or those with square-shaped feet.

This design may not look super cool, but it's a dream come true for those who struggle in regular toeboxes.

Tongue: gusset type

Unfortunately, the Escalante Racer lacks a gusset, allowing the tongue to move freely. Although the lockdown isn't bad at all, we believe that adding at least a semi-gusseted tongue would have been beneficial, especially since this shoe is designed for faster paces.

Comfort

Tongue padding

We've demonstrated that the Escalante Racer is crafted for lightness, and its tongue is no exception.

Removable insole

We found that the footbed in the Escalante Racer is not fixed, which allows you to swap it. However, due to the unique shape of the toebox, we think that finding a replacement may be more challenging than you'd expect.
